OIL-VAPORIZING ATTACHMENT FOR STOVES OR FURNACES.

S?ECIFIGATION forming part of Letters Patent No. 592,571, dated October 26, 1897.

Application filed January 25, 1897. Serial-No. 620,636. (No model) To all 2071/0722, it may concern:

Be it known that I, THOMAS P. MARGESON, residing at Melrose, in the county of Middlesex and State of Massachusetts,have invented certain new and useful Improvements in Oil- Vaporizing Attachments for Stoves or Furnaces; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make anduse the same.

My invention relates to apparatus for generating or producing heat in stoves, cookingranges, furnaces, &c., by the combustion of vaporized oil, the vaporization of which is effected by the heat generated by the combustion.

The invention has for its object to provide a simple, durable, and efficient apparatus of this character; and it consists in the improvements hereinafter described and claimed, said improvements being embodied in a heating apparatus or attachment comprising, first, an oil-vaporizing conduit or retort composed of an oil-receiving portion formed to extend horizontally along the lower portion of the inclosing firebox or other structure and provided at its outer end with means for connection with a source of oil-supply and an oil and vapor delivering portion located above and preferably parallel with the receiving portion and provided with a nipple or nozzle which projects toward the receiving portion, and, secondly, a deflecting-plate located between the receiving and delivering portions and adapted to deflect the flame from the said nipple, the office of the said deflecting-plate being to spread and distribute the flame, so that it is fully utilized in the inclosing structure and is caused to vaporize the oil and superheat the oil-vapor in the delivering portion and also to conduct heat to the receiving portion for the purpose of vaporizing the oil therein.

Of the accompanying drawings, forming a part of this specification, Figure 1 is a sectional view showing my improved apparatus as it appears in a stove or range ready for operation. Fig. 2 is a view of the deflectingplate.

The same letters of reference indicate the same parts in both the figures.

In the drawings, 1) I) I) represent the sides and top, and B the grate, of an inclosing structure, which may be the fire-box of a stove, range, or furnace and may be of any desired construction.

0 and E represent the chief parts of the oilvaporizing conduit or retort, which is formed to be inclosed in the said structure, the said parts 0 and E being preferably made of lengths or sections of Wrought-iron tubing. The receiving portion Ois substantially horizontal and is arranged at or near the lower portion of the inclosing structure and is provided at one end with means for connection with a source of oil-supply, said means as here shown being an ordinary cap or union K at the raised outer end of the portion 0, said union being adapted for connection With a supply-pipe G, which extends to an elevated oil-reservoir F and is provided with a stopcock g. The delivering portion E is located above the receiving portion O and is connected with the latter by a tubular standard D, which is a continuation or part of the retort. The delivering portion E is provided with downwardlyprojectin g vents or nipples ff, arranged to project jets of flame toward the receiving portion 0, the said nipples ff having outlet"- orifices which are relatively very small and may be of the size commonly used in the nipples of guns which are exploded by percussion caps.

A represents a substantially horizontal deflecting plate or surface, which is located between the receiving portion O and the delivering portion E, said plate being wider than the said receiving portion and practically coextensive therewith as to length. The form and arrangement of said plate are such that the flames projected from the nipples fare discharged unbroken on the plate and are deflected thereby and distributed through the inclosing structure, the flames being deflected 9 into substantially horizontal disks, which radiate from the point of impingement of the jets upon the plate A. The deflect-ed flames are not only distributed through the inclosing structure, so as to cause a thorough utilibustion.

zation of the thermal efficiency of the fuel employed, but are also arranged to subject the delivering portion of the retort to a high degree of heat, thus causing originally the vaporization of the oil in said delivering portion and subsequently the superheating of the oil-vapor therein.

The deflecting plate A becomes highly heated by the jets of flame, and as said plate is in close proximity to the receiving portion 0 of the retort it follows that the oil in said receiving portion becomes vaporized, the oilvapor finding its way through the tubular standard D into the delivering portion, from which it escapes through the nipples f.

The operation of the device is as follows: The stop-cock g being opened to permit oil to flow from the tank F into the various parts of the retort, minute streams of oil escape through the nipples f and may be ignited either directly upon the plate A or upon paper or other combustible material which may be interposed between the plate A and the nipples. Heat is immediately generated and first vaporizes the oil in the delivering portion E, the vaporized oil being forced by its expansion through the nipples f and thereaf-. ter constituting the combustible agent. The deflecting-plate A becomes rapidly heated and the heat conducted through it acts on the receiving portion 0 of the retort, vaporizing the oil therein, so that thereafter nothing but vapor enters the delivering portion E, said vapor being continuously superheated by the eat from the flames deflected by the plate A.

It will be seen that the receiving ortion 0 nd the delivering portion E of the retort are exposed to the heat resulting from the com- Hence their walls furnish large areas of oil-vap rizing and super-heating surface, so. that the production of combustib e vapor is continuous and is sufficient in vol? me without the necessity of employing an enlarged storage-reservoir for the gas and vapor. Hence I am enabled to make the entire oil containing and vaporizing apparatus from lengths or sections of wrought p pe or tubing of comparatively small diameter, so that the construction is very simple and inexpensive.

The plate A, located between. the receiving and deliveringportions of the retort and arranged'to distribute the flame so as to insure the maximum therma ciency of the combustion within the inclosing structure, also insures the heating of both parts o the roetort, the receiving portion being heated by conduction hrough e plate and the e iveringportion by upward radiation.

Owing to the above-described arrangement for effectively heating all parts of the retort, I find that there is no liability of obstruction of the retort or the nipples f f by accumulations of sediment in the retort, all foreign matter contained in the oil being apparently consumed by the high degree of heat to which all parts within the inclosing structure are subjected.

The device can be easily adapted for immediate use in any heat-producin g apparatus in which wood or coal is used. It can be introduced into any cooking stove or range when constructed as shown in the drawings, and the same device may be as readily used in a furnace by changing the plate A from an oblong to a circular form, the receiving and delivering parts being correspondingly formed.

As here shown, the outer end of the receiving portion 0 is closed by a cap II and the ends of the delivering portion E by caps e e, the standard D being connected with the receiving and delivering portions by T-joints o and h. I donot limit myself to this construction, however, as the same may be variously modified without departing from the spirit of my invention.

The plate A is or may be supported by legs or yokes a a, formed to rest on the grate B.

I prefer to make the plate A removable from the retort, so that it can be removed and a new one substituted, if desired. The plate is preferably of hardened steel to make it suitably refractory. It will be seen that by using a refractory plate in close proximity to the receiving portion of the retort, which plate is directly acted on by the jets of flame an d sr butes said jets, so that they ad ate hea pon the delivering portion of th retor I insure the effi ient heating of al p ti ns ithout direct impingement o the flame upon any po t on of the retort, thus p ev n g ability of burning out the retort, the plate A being readily removable if injured by the di oot mp ngement of the flames. up n I o aim In an apparatus of the character specified, the combination of receiv ng re ortp rtio a delivery retort port-ion l at d above sa d receiving portion and provided with a j et-orifice adapted to discharge toward the latter,

and a protecto and deflector situ te be ween the two portions and contiguous to the receivng portion, the dis ance be wee e j t-o fioo and the protector and defle o being such hat t e jet of vap r ill discha ge unb oke upon the atter, subs antially a set h.

I te timo y that I claim the for g ng as y own I have affi ed my s gnatu e in he presence of two. Witnesses. THOMAS, P. MARGESON.
